Gifts from Santa

Our cat Santa, is apparently attempting to follow his name sake. Every few of days I am finding new objects at my door of the morning, from wool to blankets.
this morning however was unique! he was been quite annoying in the middle of the night crying at my door and such (i ignored him)and i awake to fine a some of mums knitted toys lined up nicely.
so the cat managed to bring these toys up the stairs and to my door.... what exactly were these toys doing to demand such a drastic action? Oh and uni is going good to :)
